Paradise P300 Change, Tx/Rx, Service, Closed Net, Plus ESC, BA Menu, Normal, Same async ESC rate

If No ESC is chosen then the dialogue ends here, otherwise it proceeds with the Backward alarm option as follows:

	Backward Alarm facility:[?]
	1=Normal (Back' Alm) 2=No Backward Alarm
	Change, Tx/Rx, Service, Closed Net, Plus ESC, BA Menu
NORMAL	A Backward alarm facility is provided causing a deferred alarm to be raised on
	this local equipment if the distant end Rx fails for any reason (eg local Tx failure,
	or distant Rx failure). The proportion of the overhead assigned to the ESC drops
	slightly (68% to 65%), so the overhead may increase marginally to provide the
	same async ESC rate.

NO BACK' ALM No Backward Alarm is sent (Tx) or received (Rx) and so slightly more of the overhead is available to the async ESC, lowering the total overhead marginally.

See "Overhead Rates" in section 8.7.1 on page 147 for details of the overhead percentage requirements for differing mixes of main data and async ESC data rates.
